Another open issue is the threat to limit amateur radio access to the 60-meter band (shared with commercial interests).<p><a href="https://www.arrl.org/news/deadline-extended-to-november-28-2023-for-60-meter-comments" rel="nofollow noreferrer">https://www.arrl.org/news/deadline-extended-to-november-28-2...</a>
Are you allowed to use phase to double or quadruple the effective signal "density" in the bandwidth? Or, is that part of the 2.8khz no matter how you "time" it?<p>(Not a ham. In microwave point to point space, you can usually get two customers on a direction by exploring the space around the 360 clock for angle/phase of the signal being sent, horizontal vs vertical is not uncommon)
